Put Pennzoil Plat. in a pretty dirty GDI engine at 121K. At 123K the oil was black. Changed it at 124.5 b/c I THOUGHT I smelled fuel in the gas. (Blackstone said different)

Took it to Toyota (free synth. change) and they used Valvoline MaxLife 5w30

Checked the oil at 2K (today) and its only a caramel color.

So did the PP clean up the engine so well that the Valvoline didn't have much to do as far as cleaning or

Does PP have a superior detergent pkg than MaxLife? So which might it be?

PP is a very high quality GTL synthetic, with a strong detergent package. Odds are extremely good that it cleaned up most of what was gunking up that engine, which is why it turned black.

The MaxLife, while it does have a decent detergent package and quality base stock, probably didn't have nearly as much left in the engine to clean up, after the PP did its work.

Or.... the additives in PP darken when exposed to heat faster than in Valvoline.

There is no control; so no conclusions can be drawn.

What makes you think it was pretty dirty? Is the car new-to-you?

Oil colour alone tells you very little. It's an unreliable indicator of anything, actually.

However, there's a huge difference between black-looking oil with 2k miles on it and black oil with 7k miles on it. My old STI used to turn oil dark very quickly; however, the opacity changed as the miles got on. 7k-mile-old oil looked pretty gross and indicated pretty much depleted in UOA.

On the clean non-burning oil engine i dont find PP getting dark very fast, i find it stays in color longer than standard M1. However, it may not last that long, the PU i used is quite black and make engine noisy in 7k km.

This fits with my eyeball method. When draining, if I can see through the thick stream at all I know the oil had a bit of life left. If I drain and its tar black and opaque I know it's loaded up and used up.

I did an engine flush today and the drain came out opaque. That's what I expected even though it was just a 3k oci

The PUP in my 2014 Ram still looks clean as new after 4K miles on the oil.

"PP" darkens remarkably slowly in my car, but so did previous oils (TGMO and Rural King, aka Warren synthetic).

I wonder why yours is so rough on oil. Mine still looks pretty good after 4,800 miles so far on this oil change.

The pp either cleaned better or it was too thin.

I ran Pennzoil Platinum 5W-30 in my sister-in-law's Hyundai Elantra for a 5,000 mile interval and when I dissected the oil filter I was amazed at the carbon that was trapped in the pleats. I have never seen this engine produce any amount of carbon resembling this one specific interval.

I believe that the Pennzoil Platinum simply does an incredible job at cleaning the engine internals. The car is a 2002 model with 120,000 miles so it has had time to accumulate some dirt inside.
